To all whom it may concern:

Be it known that we, WVILLIAM GEORGE MAoGREGon KEIGHLEY and HARRY NETHER- woon, subjects of King Edward VII of Great Britain, and residentsof Huddersfield, in the county of York, England, have invented certainnew and useful Improvements in Machines for Cutting the Pile of WVoolen,Cotton, Velvet, or Like Corded or WVeft Pile Fabrics, of which thefollowing description, in connection with the accompanying drawings, isa specification.

This invention relates to machines for cutting the pile of weft pilefabrics, such as cotton cords, velvets and the like, in which thecutting is effected longitudinally of the fabric.

The object of our invention is to provide improved cutting means soconstructed and arranged that fiber cannot get between the actingsurfaces, the cutter head or heads being mounted so as to be easilymovable away from the fabric when the cutter guide pierces the body orfoundation thereof, the downward displacement of the cutter head orguide in piercing or cutting through the foundation of the fabricbringing into operation means to effect the stoppage of the machine.Suitable means are provided for traversing the endless fabric throughthe machine and under the cutter to give proper tension thereto; toadjust the positions of the parts for cutting each successive race, andto stop the machine after cutting each race.

Our invention comprises an improved cord or velvet cutting machinespecially arranged and constructed for the employment therein of acircular cutter or cutters suitably mounted and acting in conjunction Iwith a blade and guide to cut the pile as the fabric is traversed underthe said cutter, the cutter being stationary during the cutting actionbut, especially for velvets and the like, receiving intermittent rotarymovement to present a fresh cutting edge to the work at the commencementof each race, or at any given time, or the cutter may receive as lowcontinuous rotary motion. Then the cutter is rotated continuously, themotion must be so slow that the cutter is substantially stationary sofar as its cutting action is concerned, but the very slow motion bringsnew cutting surfaces into operation. When the cutter cuts by beingrevolved it is not suitable for velvet, although satisfactory forknitted fabrics which are made with coarse yarn. Attempts have been madein this class of machine to cut cords or velvets with a stationary orrotary circular cutter, especially the latter, but, so far,unsuccessfully, by reason more particularly of the fiber collectingbetween the guide and cutter and preventing the proper cutting of thepile. By our improvements we have overcome the difficulties which havehitherto prevented the practical working of a machine of this circularcutter type and are enabled to cut cords or the like with a circularcutter as effectually a swith the ordinary stationary cutting knife, anintermittently rotating or very slowly revolving circular cutter beingespeciallysuitablefor cutting velvets or like pile goods, as the cuttingedge in contact with the pile is being periodically or constantlychanged and therefore no injury is done to the pile as is the case whenout by'the knife or cutter now employed, and which, by reason of havingto be frequently resharpened, causes the cut pile to show a differencewhere the dull knife edge finishes and the re-sharpened edge commences,and affects the value of the fabric.

The various novel features of our invention will be fully described inthe subjoined specification and particularly pointed out in thefollowing claims Figure 1 is a side elevation of a cord or velvetcutting machine embodying our improvements, the back brake mechanism,illustrated in Figs. 3 and 4, being omitted; Fig. 2 is elevation of aportion of the opposite side of the machine, showing the rope drive, andthe mechanism for operating the screws to traverse the cutter head andthe tension device simultaneously transversely across the machine; Fig.3 is a side elevation of the back brake mechanism; Fig. 4 is an end viewof same, looking in the direction of arrow a Fig. 3; Fig. 5 is front endelevation, partly in section, looking in the direction of arrow Z),'Fig.1, of the friction driving mechanism by which motion is imparted to themachine, and which also comprises the front tension roller brake; Fig. 6is a longitudinal section of the front end of the machine, showing thecourse taken by the fabric, and also the device for moving the tensionbelts, and the contact device for operating the electric stop motionwhen the guide penetrates through the fabric; Fig. 7 is a front view ofthese last mentioned parts taken in the form of a section on the line c,0 Fig.6, looking in the direction of the arrows; Fig. 8 is a plan viewof the parts shown in Fig. 6, with the driving arrangements for same;Fig. 9 is a side elevation of the tilting cutter head, cutter and parts;Fig. 10 is a plan view of the cutter plate showing the cutter and parts;Fig. 11 is .a part sectional elevation of the circular cutter and knife,showing the cutting edges; Fig. 12 is an enlarged plan view of thecircular cutter and. knife; Fig. 13 is plan view of a modified form ofcutter head; Fig. 14 is a side elevation of Fig. 13 showing the cutterin its operative position; Fig. 15 is simi lar elevation to Fig. 14, butshows the cutter in inoperative position; Fig. 16 is a side elevation ofthe mechanism for stopping the machine on theeutter being removed fromthe operative position or the guide piercing the fabric; Fig. 17 is aplan view of Fig. 16;.

Figs. 18 and 19 are detached details showing the catch on the end of thestop wire attached to the tilting cutter head, and Fig. 20

is plan view of the circular cutter showing one embodiment of means forintermittently rotating the cutter; Figs. 5 to 20 are on an enlargedscale.

Referring to the drawings, 1 represents the framework of the machine, 2the delivery roller, 3 the feed roller, and 4 the tension roller, whichispositively driven. by means of the main shaft 5 on which it ismounted, and to which motion is imparted by means of the frictiondriving mechanism to be hereinafter described. The fabric A which ismade endless, is guided under a roller 6 loosely mounted in bearings inthe framework to the roller 2 and after passing over the said roller itis conducted under a roller 7 similar to the roller 6 and from thenceover the feed. roller 3. After leaving the feed roller it passes over abar 8, which is placed just in front of the cutter and steadies thefabric while the cutter is operating. From the bar 8 the pile fabric, arace of the pile of which has now been cut, passes over the positivelydriven tension roller 4, and thence over a second tension roller 9 whenit is acted upon by the revolving brush 10. The brush 10 directs it onto the inclined board 11, which delivers it on to the endless belts 13passing around. rollers 14 and 15 at the front and rear of the machinerespectively, the belts 1.3 resting between these two rollers, onrevoluble roll ers 17 supported at each side of the machine in a frame17. Motion is imparted to the roller 14, to cause the belts 13 totraverse the fabric towards the rear of the machine, by means of bevelgears 14, shaft 12 and worm gears 14 the worm of the said gear beingdriven by a belt 14 passing around a pulley or disk 14 fast to the saidworm, and around a pulley 14 forming part of the friction drivingmechanism. Instead of the arrangement of endless belts and rollers justde scribed, any suitable form of scray or travel ing apron or conveyermay be employed to traverse the fabric underneath the machine. Afterleaving the endless belts and rollers, or the scray, the folds of fabricare caught between the self-adjusting drum or cylinder 18 and a seriesof ropes or belts 19 passing around the roller 15 intermediate the belts13 and loosely mounted guide rollers 20. This causes the folds of thefabric to be carried to the top of the drum 13' and from thence it isconducted over and under guide rollers 21 and the roller 6 back to thefeed roller 2. The inclined board 11 is pivoted at 11 to enable it to beturned over to direct the fabric out of the machine instead of on to thescray.

Having thus described the course of the ,fabric through the machine, wewill now describe the means suitably tightened or put under tensionlongitudinally in order that the cutter may act. This portion of ourinvention is shown most clearly in Figs. 2, 5, 6 and 7. The fabric isstretched longitudinally between the delivcry and feed rollers 2, 3, andthe tension roller 4, by meansof a brake drive comprising the groovedpulleys 3 and 2 respectively, loose on the shafts of the feed anddelivery rollers and around which passes a rope 4 driven from a pulley 4on the tension roller shaft; The rollers 3 and 2 are provided withratchet wheels 3 and 2 into engagcment with which are pressed,by meansof springs, the pawls 3 and 2 pivoted on the backs of the groovedpulleys 3 and 3 to rotatively connect the rollers and pulleys in aforward'direction so that said rollers cannot rotate at a quicker speedthan the pulleys are driven at. So long, therefore, as there is therequired amount of tension on the fabric, the feed and delivery rollersrotate with the grooved pulleys on their respective shafts, but shouldthe tension become abnormal, as

for causing the fabric to be p way and fails to rotate the rollers 3, 2,at the same speed as the pulleys 3, 2, the latter are free to revolveindependently of the rollers, the pawls 3 2 riding harmlessly over theteeth of the ratchet wheels until the requisite tension is againreached, when the pull on the fabric increases the speed of rotation ofthe said rollers until locked'to the pulleys by engagement of the pawlswith a tooth of the respective ratchet wheels, whereupon the rollers andpulleys again rotate together at thesame speed.

A carrier pulley 22 and tension pulley 23 are provided. to keep the rope4 in suitable contact with the surfaces of the respective pulleys. Therope 4 also drives the roller 9 and brush 10. In addition to puttingtension on the fabric by -means of the brake drive just described, weput extra longitudinal tension on the fabric just at the particularpoint in its width where the cutter is operating. For this purpose, weprovide a tension belt 24 see Figs. 6 and 8 passing around the tensionroller 4 and around a supplementary roller 25, and another tension belt26 passing around the feed roller 3 and around a supplementary roller27. The belts 24 and 26 are arranged in line with the cutter to raisethe portion of fabric on which the cutter is operating slightly abovethe portion on either side thereof and thus put extra tension on to thatparticular portion. The belts 24 and 26 touch the fabric only at distantpoints, and do not extend for an distance in contact with it. When asingle belt is used which extends longitudinally in contact with thefabric and under the pile cutting devices its action is notsatisfactory. It is also found that a stationary support over which thefabric is dragged injures the back of the fabric. As the belts 24 and 26pass over the rollers 3 and 4, which are sometimes revolved at slightlydifferent speeds, each belt partakes of the exact speed of the roller towhich it pertains, and the fabric is not dragged over any stationarysupport. The belts are moved transversely across the machine in unisonwith the cutter mechan ism by means of the belt forks 24 and 26 (Figs.6, 7 and 8) carried by a bracket 28 having a nut formed therein whichworks on a screw 29 rotated by means of worm and worm wheel 30 from theshaft 31 by means of which, and worm gear 32 at the rear end of themachine (see Fig. 2), the screw 33 for traversing the cutter mechanismis operated. The lower end of the bracket 28 is supported and slides ona transverse rod 28. The supplem entary rollers 25 and 27 arej ournaledrespectively at either side of the machine in blocks 25 and 27 mountedon screws 25" and 27" (Fig. 1). The position of the blocks 25 and 27 canbe adjusted to tighten or slacken the respective belts by means of handwheels 25 and 27 (see Fig. 2) operating through trans verse shafts 25and 27 and worm gears at either side of the machine to rotate the screws2 or 27 in one direction or the other.

The cutter comprises a circular disk 34 having a cutting edge 34 mountedon a shaft or spindle 35 carried by a plate 36 having a projecting studor spindle 36 which is secured in the aws 37 formed on the tilting head37 by means of the spring fingers 38, which permit of the cutter beingremoved from the machine for sharpening or other purposes and also admitof the cutter and parts swiveling about said stud or spindle 36, wherebythey will follow the race accurately and give or turn to any slightdeviation in the-race.

The tilting head 37 is pivoted at 37 projection 39 from the end of theradial arm 39 whose opposite end is pivoted on the vertical projection40 carried by the bracket or pedestal 41 mounted on the screw'33 beforementioned. A bowl 39 carried by the arm 39 rides on the bar 39 which issupported by brackets at either side of the machine and acts to steadythe said arm 39. Rotation of the hand wheel 31 on the shaft 31 throughthe worm gears 32 and 33 thus causes the bracket or pedestal 41 carryingthe cutter arm to be moved. transversely across the machine, to move thecutter from one race to the next succeeding race, and through the wormand wheel 30 and screw 29, causes the tension belts 24 and 26 to bemoved in a corresponding manner. The hand wheel 31 is operated aftereach race has been cut to move the cutter and. tension belts a shortdistance transversely to enable a fresh race to be out. To the lower endof the tilting head 37 is secured one end of a wire or rod 42 whoseopposite end is provided with-a catch 42 (see Figs. 16, 18 and19)'adapted to engage a shoulder 43 on the support 43 fixed to theprojection 40. The engagement of the catch 42 on the wire or rod 42,with the shoulder 43, holds the cutter in position for cutting, that isto say, in the position shown in full line Fig. 9, and the release ofsuch catch causes the cutter head by means of the spring 44 to be tiltedto lift the cutter clear of the fabric, that is to say, into theposition shown in dotted line in Fig. 9.

The catch 42 is held in engagement with the shoulder 43 by means of alever 45 pivoted at 45 in bearings carried by the bracket 41, one end ofthe said lever being provided with a plate 45 adapted to rest upon theupper side of the catch 42, and the other end of the said lever beingprovided with a cross piece 45 forming the armature of an electro magnet46.

47 is a bowl carried by a lever 48 pivoted at 48 to the vertical arm ofthe bracket 41, the bowl engaging the rear end of lever 45 and beingheld against same under the tension of the spring 49. 50 is a plateextending transversely of the machine and secured to a rock bar 50 toone outer end which is also secured an arm 51 (Fig. 1) having connectedthereto a link 52 which is pivotally connected to a link 53 pivotallyattached to the stop lever 54 having an extension 54 and mounted at 54on a stud on the side frame of the machine. A lever 55 pivoted on theboss 48 of the lever 48' is forked at its lower end 55 to looselystraddle the plate 50 and has a forwardly projecting toe 55whiclrnorinally rests on the edge of the armature 45 This said lever 55is used solely to operate the stop motion by hand, the inclinedprojection 55, when the lever 55 or plate 50 is drawn forward,separating the armature to a l from the magnet and actuating the stoplever through the intermediate connections. The forked end 55 enablesthe lever 55 to oscillate the plate in each direction, whereas the lever48 arranged behind the lever can only operate the plate 50 in onedirection as it has only a single end portion to the right of the plate50 in Fig. 16. When the plate 50 is operated to move'the lever 55 to theleft to separate the armature from the magnet, the lever 48 is notoperated by the plate 50, but is moved to the left by its spring 49 whenthe armature has been moved downward sufficiently to make room for theroller 47.

A stop piece 42 on the rod or wire 42 is provided to engage with the endof a short tube 56 for preventing the rod or. wire from being pushed toofar rearwardly to carry the catch beyond the shoulder 43. A bracket 57having a forked end 57 embracing the radial arm 39, prevents the saidarm from swinging too far to either side.

Attached by adjusting screws 58 to the plate 36 carrying the circularcutter 34, is another plate 59 to which is attached a guide 60, thepoint 60 of which is shaped and adapted to enter the race slightly infront of the cutter 84. The point 60 is formed by beveling the top andsides of the loop-guide 60 at one end portion thereof. Resting in a slotin the guide 60 is a fixed knife 61 having its upper and forward edgesground away at an angle, as shown plainly at Figs. 11 and 1.2. The plate59 carrying the guide and the fixed knife isfadjusted to bring the saidknife close up to the flat side of the circular cutter in about thepositions shown by Figs. 11 and 12, so rhat the meeting edges of thefiXed knife and cicular cutter form an angle into which the pile passesas the fabric is carried along. The cooperation of the cutting edges ofthe circular cutter and the fiXBdkIiifG, causes the pile to be out verycleanly, and there is no lia bility of the cutter becoming choked whitfiber and failing to act. A set screw 59 keeps the knife 61 in contactwith the cutter 34. Should the cutter guide 60 penetrate through theabove, it contacts with one or other of a series of wires 62 secured toa plate 62 pivoted on a frame 63 carried by the bracket 28. These wiresare in circuit with the electro magnet 46 around the cores of which twoseparate wires are coiled, one over the other in opposite directions, aweak current normally passing through one of the wires to energize themagnet to attract and hold the armature 45 When the cutter guide 60contacts with one of the wires of the series of wires 62, a circuit isthus completed and a stronger current then passes through the secondwire which momentarily demagnetizes the cores of the magnet, whereuponthe lever 45 is released and the heavier rear end thereof rocks it uponits fulcrum and swings the front end thereof upward away from and clearof the catch 42, and the rear end clear of the bowl 47 on the lever 48.Immediately this takes place, the lever 48 ispulled forwards by thespring 49, the bowl 47 on said lever riding up the inclined edge of thelever 45 and holding the opposite end of the lever clear of the catch42. The forward movement of the lever 48, through the. projecting finger48 thereon, causes the plate 50 to rock the bar 50 carrying the same, inits bearings, and through the connections 51, 52, 53 (Fig. 1), toactuate the stop lever 54 to stop the machine. A bell (not shown) incircuit with the wires 62 and electro magnet 46, is rung when the guidepierces through the fabric.

To replace the catch 42 into engagement with the shoulder 43, the wire42 is pushed rearwardly by hand until the catch is over the saidshoulder, when the stop lever 54 is pulled forwards to cause the plate50 to rock the lever 48 in the opposite direction to return it to itsnormal position. This frees the lever 45 which is thereupon attracted bythe magnet and rocks the said lever 45 so as to cause the plate 45 tobear upon the upper side of the catch 42 and hold it in engagement withthe shoulder 43 to keep the cutter in operative position.

In the modified form of cutter head shown in Figs. 13. 14 and 15, asliding motion is employed instead'of a tilting motion to carry thecutter clear of the fabric in the event of the guide piercing thebacking of the fabric, or it being necessary to withdraw the knife forany purpose. In the arrangement shown, the cutter head comprises tworods or bars 37 on which a bearer 57 carrying the cutter plate isadapted to slide. The rods or bars are set at an angle to the plane ofthe fabric as shown in Figs. .14 and 15, so as to raise the cutter clearof the fabric when the bearer is in its rear or inoperative position.The cutter plate 36 is provided with a forwardly projecting extension 36to which is pivoted a lever 64 whose lower end is fashioned to form aguide 64 adapted to travel in the cut race of the fabric and rest on thebacking of the same. When the cutter guide misses a portion of the pileor makes a slip, the adjustable pin .65 carried by the lever 64 willcatch against the uncut pile of the race of the fabric and rock the saidlever 64 on its pivot. This movement of the lever 64 causes the upperend 64 thereof to abut against the plate 66 fast to the rods or bars 37,and the pressure of. the traveling fabric causes the wire 42 fast to thebearer 37 to be operated to .release a catch similar to that describedin connection with the tilting cutter head. As soon as the catch isreleased, the spring 67 draws the bearer, and with it the cutter,rapidly into the position shown in Fig. 15,

that is to say, clear of the fabric. The wire 42 in this case is carriedinside the radial arm 39.

In order to give intermittent rotary mo tion to the circular cutter 34,we secure on the axis 35 thereof a worm wheel 35 (see Fig. 20), withwhich meshes a worm 35 fast on a vertical shaft 35 supported in bearingson a convenient part of the tilting head and carrying at its upper end aratchet wheel 35. On the shaft 35 is pivoted a lever 35 carrying a pawl35 adapted to engage the ratchet wheel. The attendant on moving thetilting head and parts into operative position, presses with-the fingeror thumb against the free end of lever 35 and moves it partially around,the pawl 35 engaging a tooth of the ratchet wheel and turning itpartially round,

whereby motion is transmitted through shaft 35 worm 35 worm wheel 35 andthe shaft or spindle 35 to partly rotate the circular cutter 34 andpresent a fresh cutting edge to the work, the intermittent rotarymovement of the cutter avoiding stoppage for re-sharpening andpreventing any marking or differ ence of cut of the pile,

Referring more particularly to Fig. 5, the friction drive mechanism bywhich motion is conveyed to the shaft 5, comprises a friction disk 71fast on the shaft 5 and having a sleeve 71 on which is loosely mounted apulley 72 driven by belt 73 from any convenient source of power.Slidable longitudinally of the shaft 5 is a sleeve 74 having an annulargroove 75 therein to receive studs 76 projecting from the upper forkedend of a vertical actuating lever 76. Fast on the grooved sleeve 74 is apulley 14 from which the endless belts or scray for traversing thefabric underneath the machine, are or is driven, as previouslydescribed. 77 represents a friction disk fast to or forming part of thepedestal 1 in which the shaft 5 is journaled. 78 represents a disk orclutch member fast to the shaft 5 to rotate therewith, but slidablelongitudinally on a spline, and provided with projections or studs 7 8extending into openings 7 4 in the web of the pulley 74 to clutch thesaid pulley and the sleeve 74 to the shaft 5. The lever 76 is pivoted at79 to a bracket 80 fast to the machine frame. Pivoted to one another at82, and at their other ends to the lever 76 and to the lever 81respectively, are a pair of toggle levers 83, 84. On the pivot stud 82of the levers 83, 84, is pivoted the upper end of a vertical rod or bar85 having a slot at its lower end through which passes a stud 86 securedto a counter-balanced treadle lever 87 pivoted to the frame at 87. Thetoggle levers 83 and 84 have stop lugs at their meeting ends, and 83 isan adjusting screw which engages with the said lugs. This screw preventsthe toggle levers from foldingv downward, but permits them to be foldedupward when the rod 85 is pushed up. The toggle levers are pivotedtogether and to the said rod at their meeting ends in any approvedmanner. The lever 81 has pivotally connected to its upper end a rod 88,

aving a spring 89 confined thereon by adjusting nuts 90, which permit ofthe pressure of the spring 89 being adjusted to compensate for wear ofthe friction disks 71 and 77. 88 is a guide lug which projects from theframe 1. The rod 88 slides in this lug, and the spring 89 is arrangedbetween this lug and the nuts 90. In the position of the parts shown inFig. 5, the sleeve 74 is pressing the face of the loose pulley 72against the friction disk 71, and thus causing the motion of the saidpulley to be transmitted to the shaft 5 to drive the same. When the stoplever 54 is actuated, to stop the machine, the screw 91, passing throughthe end 54 of the said stop lever, comes into contact with the undersideof the lever 83 and causes the vertical rod 85 to be raised and thelevers 83, 84, to swing upward on their pivots and thus enable thespring 92 to move the lever 76 to the left. This withdraws the sleeve 74from pressing the loose pulley 72 into engagement with the friction disk71 and causes the face of the pulley 14, forming part of said sleevetobe pressed against the fixed friction disk 77 and act as a brake forthe tension roller 4. On the stop lever 54 being returned to normalposition and the treadle lever 87 depressed, the vertical rod 85 isdrawn downwards and the action of the toggle levers 83, 84, causes thelever 76 to move to the right or into the position shown in Fig. 5, torestart the machine. In order to stop the machine at the end of eachrace, a pivoted frame or plate 93 is located over the delivery roller 2.The passage of the thickened portion of the fabric caused by the joiningof the ends of the same, under this plate 93, causes it to beoscillated. By means of the finger or lever 94 on the end of the shaftsupporting the said plate, and a collar 53 fast on the connecting rod53, this movement is transmitted to the stop lever 54 to sto themachine.

The mechanism for bra ing the delivery and feed rollers (see Figs. 3 and4) comprises brake drums 95 and 96, respectively, fast on the axes ofthe said rollers, onto which a brake block 97 is adapted to be pressedby means of a brake lever 98 pivoted to the frame 1 by a pin 98. Thebrake block is shown as being in contact with the brake drums. The freeend of the brake lever 98 is raised to remove the brake block fromengagement with the drums 95 and 96 by means of a vertical rod 99actuated from the treadle lever 87 and the brake lever is maintained inits raised position by means of a pivoted latch 100 adapted to swingunder the free end thereof. On the lever 76 being operated to stop themachine, the latch 100 is removed from under the end of the brake thesaid cutter and the said knife stationary and provided with alongitudinal groove, a

' means for turning the said head automaticlever and the spring 101pulls down the free end of the said lever 98 and applies the brake block97.

For cords, velvets, or the like, woven in two or more widths, a cutterand parts can be employed for operating on each width, or, for cuttingcords alone, two or more cutters may be employed for each width offabric.
